Last Words of a Killer: Seung-Hui Cho's Shocking Diatribe

In a package to NBC, Cho offered his own distrubing profile.

Excerpts From the Tape Cho Sent to NBC News

On the video, Cho's voice is at times inaudible. He also becomes aggressive and at one point uses profanities. He mentions the martyrs Eric Harris and Dylan Klebold, both from the Columbine shootings, in the video. His violent poses in the photographs, at left, suggest that he mimicked aspects of the Columbine murderers. (NBC/AP Photo)
